Pew surveyed 3,014 adults between Aug. 7 – Sept. 6 and found that 45-percent of American adults own smartphones.

So, perhaps, that could still give a little bit of hope to Microsoft whose market share for smartphones comes in at a dismal 3.6 percent.

As expected, smartphones are most popular in the 18-to-29 year-old age range, with 66-percent of young adults owning one. Annual household income also goes hand-in-hand with smartphone ownership — the higher the income, the more likely the person owns a smartphone. About 68-percent of those earning more than $75,000 own one.

It does appear that smartphones are replacing feature cell phones — devices that have capabilities to text and call, but not more advanced functionality. About 34-percent of Americans own a feature phone, which is 12-percent fewer than those with smartphones.

Some (5-percent) still do not know if they own a smartphone, and there are those who live without a cell phone. Pew found that 15 percent of American adults do without one.
